context.objectFile[ReIdDataSetEntry]("data") -not sure how this is compiled
in scala. But, if it uses some sort of ObjectInputStream, you need to be

ClassLoaderObjectInputStream to workaround this.On Wed, Mar 26, 2014 at 1:38 PM, Jaonary Rabarisoa <jaon...@gmail.com>wrote: > it seems to be an old problem : > > > http://mail-archives.apache.org/mod_mbox/spark-user/201311.mbox/%3c7f6aa9e820f55d4a96946a87e086ef4a4bcdf...@eagh-erfpmbx41.erf.thomson.com%3E > > https://groups.google.com/forum/#!topic/spark-users/Q66UOeA2u-I > > Does anyone got the solution ? > > > On Wed, Mar 26, 2014 at 5:50 PM, Yana Kadiyska <yana.kadiy...@gmail.com>wrote: > >> I might be way off here but are you looking at the logs on the worker >> machines?
